Description:
OC-F08 series Split type fixed gas detector, the shell and sensor is connected by the cable, the normal length is 60~80cm, but can be customized for special applications. The split type gas detector can be used to detect the closed space gas concentration, the sensor part can be placed in the inner closed space, the shell installed out of the closed area and displaying the gas concentration data.
The separate type fixed gas detector also used the original imported sensor and the ultra low power 32 bit microprocessor, so with the advantages of high precision, good repeatability, stable signal, respond quickly, etc. Possible connected with many controller system, such as PLC, DCS, computer and other, with the function of remote monitor and alarm, data logger and analysis.
Features:
4-20mA standard analog signal and RS485 digital signal output, 200~1000HZsignal output, relay output, data restore, data logger(optional);
LED screen displaying the gas concentration, gas type, unit, instrument status etc.
Independent air chamber, the sensor is not required to replace the sensor calibration, automatic identification of key parameters of the sensor;
Protection function to prevent high gas concentration attack;
Display the gas concentration in ppm, %LEL, %vol and mg/m3 is selectable;
Infrared remote controller operation;
With the 16bit ADC acquisition chip, designed with four-layer circuit board, so with high anti-interference ability;
With the Ex-proof certificate, the Ex-proof grade is Exd II CT6.
